ah, this seemed intriguing to me, so I did some research, and you didn't want an opinion Dave, you wanted a fact, so I just got done talking with the people over at the microsoft knowledge center to find out...sp1 does nothing to change the mechanics of the pagefile.

so, now I went on to do some reading for you dave...according to the resource; "microsofts windows xp professional (resource documetation kit) published by the microsoft press,
the only differance between th pf in xp, and 2000, is that xp recognized that the default pagefile in 2000 was too small for most users, and it thus increased the default size for it.

it then goes on to say that it would save space, and it asks the reader to referance "inside 2000" for a complete understanding of the pagefile mechanics
